Seethalakshmi K, Jasmine Vasantha Rani E

Abstract: Thermodynamic and electrochemical properties of salts find extensive application in characterizing physico-chemical properties. This paper deals with the thermodynamic and electrochemical behaviour of solutions of some imidazolium salt solutions. Measurement of density, viscosity and ultrasonic velocity leads to the determination of internal pressure which tells about the interaction between molecules and ions. Specific conductance values are also measured for studying ionic behaviour of the solutions. All the measurements are carried out for various concentrations of the solutions in the temperature range from 278.15 K to 328.15 K. These parameters provide the sufficient information about the interaction between the ions and molecules of solvent.
